Found this om youtube;

The title of the work is named 'Alma redemptoris Mater'. Before I listened to it, I thought it was a CD copy from one of the two recorded works by the same name, Zwv 123 or Zwv 124. But this was indeed not one of those two. Listening to it, I searched in "Find a work" from this website and concluded theit must be Zwv 127. It sounds very Zelenka. Nicely preformed.
Anyone else not heard this before ?
